OIL-CAN `FAUCET.

SPECIFICATION forming part of Letters Patent No. 521,491, dated June 19,1894.

Application filed February 28, 1894. Serial No. 501,818. (No model.)

To @ZZ whom it may con/cern,.-

Be it known that I, GEORGE W. AEPEE, a citizen of the United States,residing at Oakland, in the county of Alameda and State of California,have invented certain new and useful Improvements in Oil-Can Faucets;and

lafter the valve of the faucet has been closed in order to cut -off theoutflow of the liquid; and the inventionconsists essentially in formingor connecting an air chamber directly with the faucet,into which chamberan air vent tube extends, said tube running from the outer end of thefaucet into the chamber, the chamber discharging the air conveyedtherein into the oil vessel through the outlet passage provided for theescape of the oil therefrom.

In order to more fully understand my invention reference must be had tothe accompanying sheet of drawings which form a part of thisapplication.

Figure 1, is a sectional view showing my faucet connected to an oil can,the valve being closed and the lower corner of the can being brokenaway. Fig. 2, is an enlarged detail view of Fig. 1, the valve beingopened v forms an outlet for the oil retained within the can. This bossis screw-threaded externally, as shown vat a, to which is screwed theenlarged head B, of the faucet, the spout or nozzle B', of which extendsdownward below the bottom of the oil can. The inner portion of the headB is cut or cored outso as to provide an air chamber O, which is ofgreater diameter than the outlet passage of the can. Into this chamberextends the air vent tube C',

ber C,l as shown. Through a screw-threaded opening c', extends thescrewthreaded valve stem D, to the inner end of which is secured thevalve D', which is held in place by nut c2. This valve is made of softmetal and seats itself, when moved inward its full distance, against theraised lip d, of the boss A', and when seated serves to prevent theescape of oil from the can. To the outer end of the valve stem issecured the hand wheel Dby means of which the valve is moved in or out.

By making the valve of soft metal and removable I am enabled to easilyreplace the same when worn out and to dispense with the use of a'packing ring for the reason that the raised lip of the hard metal boss,will cut within the soft metal valve and thus make atight joint.

In the outer portion of the valve stem I cut the groove E, whichconnects the enlarged air chamber with the outside atmosphere when thevalve is seated. The grooved portion of the valve stem only extendswithin the air chamber when the valve is closed. This groove serves asan air passage for venting the air chamber when thevalve is closed inorder to provide against the vent tube becoming gorged.

yIn Fig. 3 I have shown a modication of the faucet. In this case theboss E, constitutes the air chamber into the lower end of which thespoutB', is secured. From the lower end of this spout is run the air venttube C', which discharges intothe air chamber. Upon this spout is thescrew-threaded collar E. When I make employmentY of this form of faucet,the lower end thereof and of the air vent tube is closed by the valveE2, carried by the sleeve F, which fits over the spout and is held inplace thereon by cap F.' The sleeve works up and down upon thescrewthreaded collar. This style of faucet is fully set forth anddescribed in an application filed by me on the 17th day of October,1893, Serial No, 488,387.

By screwing the faucet to the boss, as shown which runs from the lowerend of the spout 1 B and terminates near the top of the cham-v IOO inFigs. 1 and 2, I am enabled to swing the faucet at a right angle to thecan, as shown in Fig. 1 by dotted lines, and in this manner raise thespout so as to permit the can to be placed upon a oor,whicb it could notdo if the spout projected below the bottom of the can. As the valve ofthe faucet is openedto permit the outflow of oil from the can,the airtube immediately takes air, discharges same into air chamber, fromwhence it enters the can through the outlet opening and thus Vents thesame. The lower end of the spout is inserted into the reservoir of alamp or other vessel, and, after the liquid reaches a certain level, thelower end of Vent tube is. closed by being submerged within the oil.This sub merging automatically stops the dow of oil,

byclosingthe'vent tube, and thus prevents the overilling` of the vessel.Asthevalve is closed theair chamber is vented through the groove inthevalve spindle, which serves to expel any oilwhich may be in the airventtube.

Having thus described my invention, what Iclaim as new, and desire tosecure protection in by Letters Patent, is-

1. The combination with a faucet fordrawing oif the contents of oil cansand similar packages, of an air chamber communicating with theinteriorof thecan directly connected with the faucet, an air Vent tubeleading from the end of the faucet spout into theair chainber, andthecut o valve of the faucet.4

2. The combination with an oilcan or similar vessel, the boss projectingtherefrom, an air chamber formed within the boss the faucet movablysecured to the boss so as to be swung at right angles to the can,whereby the end of the faucet may be carried above the bottom of thecan, said faucet connected with the air chamber, the air vent tubeleading from the end of the faucet into the air chamber and the cut offvalve for the faucet.

3. In a faucet for drawing off the contents of oil cans or similarpackages, the combination with the air chamber, an air vent tube and avent tube leading from the lower end of the spout into the air chamber.

In testimony whereof I a-iix my signature in presence of two witnesses.

GEORGE W'. ARPER.
